To find what she saved you need to subtract 500-325= 175 then take 175 divided by the original price (500) to get a percentage so 175÷500=0.35 0.35= 35% so your answer is she saved 35%
Work= forcexdistance force=55x10(or 9.8 depending on which gravitational field strength you use) force= 550N work = 550x0.2 work= 110J six steps=110x6=660J
